Not sure if this will help or not, I wrote to them and got the answer back the next day. Was shocked by the answer... but it was quick never the less

We are a UK company currently focused on our home market (due to the sheer scale of demand for the product here). The market place being global we have customers in the US but as we have no support on the ground there yet our threshold for clients in the NA region is that they must turnover in excess of $1.5M per annum. If this excludes you at this stage please accept our apologies. We are scaling our business and do plan to enter the market there in the near future but as a young company it is important to build our foundations here first. Once we can support a broader community there and lower this threshold we will, of course, be back in touch.

We are in the processing of beta testing the new version of the software which will also allow the import of sales from a CSV file - if you get a CSV file of your orders, the new version will be able to import it.

The version you'll need to work with all 3 platforms is £595 with an annual license of £215 payable on the anniversary of the purchase.

The products can be 'mapped' to stock records in Line 50. There are a couple fo ways to do this but most of my clients use the Custom Label field on eBay to store their Sage Stock Code and do the same with the SKU on Amazon,
